Dichloromethane → 4-(6-Chloropyridine-3-carbonyl)morpholine

Participants

Reaction Steps

To a solution of chloronicotinoyl chloride (3.52 g, 2.00 mmol) and triethylamine (3.1 mL, 2.22 mmol) in dichloromethane (5 mL) at 0° C. was slowly added morpholine (1.75 mL, 2.00 mmol). The mixture was warmed to ambient temperature, washed with water (2×25 mL), brine (1×25 mL), dried (Na2SO4), filtered and concentrated under reduced pressure. The product was chromatographed on silica with ethyl acetate to give the titled compound (4.0 g, 88%). MS (DCI) m/z 227 (M+H)+;
